You can take up to 3/d of the 100mg tabs (up to 6/d of the 50mg) for up to a week . It will continue to soften the stool your body is making as well as what's already there. Drink as much water as you can stand...adding lemon or ginger will help the process and may make the water more palatable/less nauseating. You could also add a glass or two of prune juice per day (wait until you have a bm though...it can cause worse cramping if you're already impacted).
Really hoping it works for you soon !
The 2nd tri is way better, I promise...hang in there !
